Amazon is rolling out an update for its Alexa mobile app that brings some new functionality and relocates the activity history.
Prior to this update, whenever you opened the app, the activity history page, along with information cards, were the first thing to see. Now, a brand new Daily Updates screen is launched when the app is run. And, you can always come back to view the Daily Updates using the card stack icon at the bottom of the screen.
Looking for the old-style Activity history? You can still find it under the Settings menu: Settings – Activity
